Question

please tell answer this is very difficult​

Answer 1

radius =√6x.......

pir²=pi(2+6x+9)

Answer 2

Answer:

Radius = 3x

Step-by-step explanation:

Area          

  $=\pi x^2+6\pi x+9\pi \\=\pi (x^2+6x+9)$

We know, the area of a circle is $\pi r^2$.

∴ $\pi r^2=\pi (x^2+6x+9)\\\\ r^2=x^2+6x+9$

   $r^2=x^2+3x+3x+9\\r^2=x(x+3)+3(x+3)\\r=(x+3)(x+3)$

$x=\frac{r}{3} \\r=3x$
